DESCRIPTION, CIRCUIT
2
DESCRIPTION The Stack Valves described in this bulletin can be used as vertical and horizontalstack systems.
As pressure relief, pressure reducing valves, throttle valves with check, as check
and counterbalance valves they are standardized according to CETOP, ISO and
DIN in mounting configuration and meet industrial requirements for compact
control systems.
Stack valves size 03 have the same mounting configuration as the directional
control valve 4D01 and can be arranged as shown on the following pages.
